Hyperledger fabric client credential store using CouchDB

Question

I am using Hyperledger Fabric SDK for node.js to enroll a user. I am using this code to deploy in fabric. It uses FileKeyValueStore (uses files to store the key values) to s

Answer 1

There is no built-in support in the connection profile for using the CouchDBKeyValueStore, but you can still use the connection profile for the rest of the Fabric network configuration. You'll then need to use the Client APIs to configure the stores. Something like

const Client = require('fabric-client');
const CDBKVS = require('fabric-client/lib/impl/CouchDBKeyValueStore.js');

var client = Client.loadFromConfig('test/fixtures/network.yaml');

// Set the state store
let stateStore = await new CDBKVS({url: 'https://<USERNAME>:<PASSWORD>@<URL>', name: '<DB_NAME>'})
client.setStateStore(stateStore);

// Set the crypto store
const crypto = Client.newCryptoSuite();
let cryptoKS = Client.newCryptoKeyStore(
    CDBKVS,
    {
      url: 'https://<USERNAME>:<PASSWORD>@<URL>.cloudant.com',
      name: '<DB_NAME>'
    }
);
crypto.setCryptoKeyStore(cryptoKS);
client.setCryptoSuite(crypto);
